Learn how to implement the reactive programming paradigm with C++ and build asynchronous and concurrent applications

Key Features

Efficiently exploit concurrency and parallelism in your programs Use the Functional Reactive programming model to structure programs Understand reactive GUI programming to make your own applications using Qt

Book DescriptionReactive programming is an effective way to build highly responsive applications with an easy-to-maintain code base. This book covers the essential functional reactive concepts that will help you build highly concurrent, event-driven, and asynchronous applications in a simpler and less error-prone way.

C++ Reactive Programming begins with a discussion on how event processing was undertaken by different programming systems earlier. After a brisk introduction to modern C++ (C++17), you'll be taken through language-level concurrency and the lock-free programming model to set the stage for our foray into the Functional Programming model. Following this, you'll be introduced to RxCpp and its programming model. You'll be able to gain deep insights into the RxCpp library, which facilitates reactive programming. You'll learn how to deal with reactive programming using Qt/C++ (for the desktop) and C++ microservices for the Web.

By the end of the book, you will be well versed with advanced reactive programming concepts in modern C++ (C++17).

Who this book is forIf you're a C++ developer interested in using reactive programming to build asynchronous and concurrent applications, you'll find this book extremely useful. This book doesn't assume any previous knowledge of reactive programming.

Praseed Pai has been working in the software industry for the last 25 years, starting his career as a MS-DOS systems programmer using ANSI C. He has been actively involved in developing large-scale, cross-platform, native code-based systems using C++ on Windows, GNU Linux, and macOS X. He has experience in COM+ and CORBA programming using C++. In the last decade, he has worked with Java- and .NET-based systems. He is the primary implementer of the SLANG4.net compilation system, which has been ported to C++ with an LLVM backend. He coauthored .NET Design Patterns, by Packt Publishing. Peter Abraham has been a performance fanatic and a C/C++ programming language enthusiast right from his college days, where he excelled in Microsoft Windows programming and GNU Linux programming. He garnered experience in working with CUDA, image processing, and computer graphics programs by virtue of working with companies such as Quest Global, Siemens, and Tektronics. Peter has been eagerly following the C++ standard and RxCpp libraries as part of his profession. He has worked with cross-platform GUI toolkits such as Qt, WxWidgets, and FOX toolkit.
